I just hooked up my Zune HD AV Dock today and was surprised to see an optical output! The optical out works great. I then connected and HDMI cable and the audio output via optical stopped. I'm guessing once HDMI is connected, all audio and video is routed through HDMI. Is there a way to have video (or video and audio) out through HDMI and audio out through optical at the same time? I'd rather not listen to my TV speakers when I have a surround setup.
The way my 360 is hooked up, I get audio and video out to the TV via HDMI so I just turn down TV audio. Then I run optical out to my receiver and use that for the audio. Is there a setting or patch to get this same behavior on the Zune HD AV Dock?
